Following the morning skate, Seguin said that nothing in particular in the Bruins’ 3-1 win over the Sabres prompted his maintenance day and that he is “all good” physically.

As for the lines being reverted to what they were for the season’s first nine games, Julien said that the experiment of switching the right wings on the top two lines — something he did for the third period last week against the Canadiens to kick-start Seguin and the offense in general — is something he plans to keep in his repertoire going forward.

The Krejci line scored goals in its first two shifts in the third period against the Habs, and though Julien took a risk by breaking up a line that was flourishing with Horton, the power forward continued his strong season with a sensational performance against the Sabres while skating with Bergeron and Marchand.

“Interchangeable,” Julien said of Horton and Seguin. “I said it before — even after they came out and did a great job in Montreal, I said, ‘Listen, this could be temporary, and it could be for a while. It depends.’ There are some players there that are very interchangeable and it gives us some different options.”

Obviously, Horton and Seguin differ greatly as players. They’re both immensely skilled player (both top-three picks in their respective draft years), but Horton is a far more physical player, while Seguin’s offensive skillset is superior.

It’s those differences that allow Julien to get much different looks with a flick of the switch. Putting Seguin on Krejci’s line makes them faster, and as long as Lucic is his normal self, the line still isn’t soft. It may be more of a liability defensively, but thus far the line was a plus-3 over the last two games. Horton, meanwhile, adds more grit to an already hard-working line with Bergeron and Marchand.

At the end of the day, the B’s are still wiser to keep Seguin with Bergeron and Horton with Krejci. Any defensive shortcomings on Seguin’s end go unnoticed thanks to Bergeron, while the combination of Horton and Lucic gives Krejci’s line a bruising edge that makes them extremely difficult for opposing teams.

Either way, Julien has said that he’ll be quicker to tinker with his lineup this year than in seasons past due to the shortened schedule. It’s still early in the season, but the B’s are fortunate to know they have options that have proven to work.
